“There were some pregame nerves,” Bluder said. “It took some time to settle down.”

Iowa clung to a 28-23 halftime advantage, then ran away in the second half. Gustafson scored 24 of her game-high 34 points after intermission.

“I liked that we had the (Senior Day) ceremony afterward,” Gustafson said. “We were able to do our gameday routines, which was super helpful. There was a lot of outside stuff going on with family coming in and it being our last guaranteed last home game.”

Bluder could be excused for being doubly nervous in pregame. Adding to Sunday’s pomp and circumstance was the fact that her daughter, Emma, was singing the national anthem at Carver.

“I was so nervous,” Bluder said. “Emma, she just said, ‘Mom, I’ll see you on the court.’”

The Hawkeyes broke to a 24-11 lead, then Northwestern (16-13, 9-9) closed with a 12-4 push to get within five points at halftime.

Then, Gustafson owned the second half. She missed two of her first three shots Sunday, then made 13 of her last 14. She drained all six of her free throws and grabbed 12 rebounds.

Gustafson became the 49th player in NCAA Division-I history to score 2,600 career points. With 1,364 rebounds, she is just outside the top 25 all time. And her 82 double-doubles ranks sixth.

Bluder was hoping she could give each of her seniors their own exit from the game, their own standing ovation from the massive crowd.

“Hawk fans have been behind me even when I was injured,” said Davis, who has come back from two ACL surgeries. “I got a lot of tweets and comments on Instagram. I may not reply to all of them, but I read them all the time, and they kept me going.”

Stewart said, “When you play in Carver, it’s just different. It’s such an honor to play in front of so many fans that love you and invest in you.”

Abbie Wolf led Northwestern with 15 points.

The Hawkeyes are the No. 2 seed in the Big Ten tournament, and will face Minnesota or Indiana in the quarterfinal round at 5:30 p.m. (Iowa time) Friday at Bankers Life Fieldhouse, Indianapolis.
